Rainbow Wave Lego GBC

My first Lego Great Ball Contraption creation. Balls are surfing on a wave of 38 Lego colors. This GBC has app. 1150 moving parts.

Update Nov. 2018:
the original Rainbow has run fine with the same XL motor for 120h. But with uneven tables or dust pollution friction got higher and wave speed was lower with balls stalling on the wave. I've added extra drive gears to ensure a good wave speed. Adding the extra gears also results in a more consistent wave as I have seen in my modified wave.
